Find the solution of the following linear equations (a) 3x - 3 = 6 (b) 2(y - 9) = 4 (c) -5a + 2 = 17 (d) 3x - (4 (x+3)) = 0 (e) -1 (z - 3) = 9
Answers
a. 3x =6+3
3x =9
X =9/3
X =3
b.(y-9)=4/2
y-9=2
y= 9+2= 11

Given : Linear Equations:
a) 3x - 3 = 6
b) 2(y - 9) = 4
c) -5a + 2 = 17
d) 3x - (4((x + 3)) = 0
e) -1 (z - 3) = 9
To Find : Solve the equations
Solution:
a) 3x - 3 = 6
Adding 3 on both sides
=> 3x - 3 + 3 = 6 + 3
=> 3x = 9
Dividing by 3 on both sides
=> 3x/3 = 9/3
=> x = 3
Similarly solving others :
b) 2(y - 9) = 4
=> y - 9 = 2
=> y = 2 + 9
=> y = 11
c) -5a + 2 = 17
=> -5a = 17 - 2
=> -5a = 15
=> a = - 3
d) 3x - (4(x + 3))= 0
3x - (4x + 12) = 0
=> 3x - 4x - 12 = 0
=> -x - 12 = 0
=> x = - 12
e) -1 (z - 3) = 9
=> -z + 3 = 9
=> -z = 6
=> z = - 6
